Our ability to observe, analyze and forecast major aviation, range, and aerospace hazards (turbulence, icing, convection, ceiling, visibility, and wind shear) continues to improve each year. Nonetheless, these hazards remain a leading cause of aircraft accidents and injuries, as well as delays among commercial air carriers to this day. This session invites papers that explore the newest advances and techniques in observing, analyzing and forecasting aviation hazards. In addition, and equally importantly, the session seeks papers focused on novel methods and practices to effectively assess, model, predict and share safety-critical hazard guidance among all aviation decision-makers.
